The solar activity has been quiet over the past 24 hours. The sun is currently spotless and the X-ray flux remained below B-level. Solar activity is expected to remain at low levels for the next 24 hours.

No Earth directed coronal mass ejections (CME) were observed over the last 24 hours in the available coronagraph imagery. The greater than 10 MeV proton flux remained at background levels over the past 24 hours and is expected to remain at low levels.

The solar wind parameters were mostly at nominal levels indicative of slow solar wind regime (300-350 km/s). The total interplanetary magnetic field remained below 6 nT, except for a very short period when it peaked at 8 nT. The Bz component varied between -5 nT and +4 nT. A recurrent equatorial coronal hole with negative polarity has just reached the central meridian. The coronal hole surface area has increased compared to the previous rotation suggesting that the high-speed stream effect is expected to be stronger than the previous rotation. The effect on the solar wind environment near Earth is expected to get enhanced on the 31st of July.

Quiet geomagnetic conditions were observed over the past 24 hours, and is expected to remain so until the arrival of the high-speed stream on the 31st of July when more active conditions are expected.
